Sure here's my trauma from trampolines, you see when I was a little goof I used to have this long rectangle trampoline, that I used to bounce on everyday, I had discovered a more fun variety of this activity at a birthday party with me and a bunch of other goofs, it was that by lifting the trampoline and letting it stand vertical on the back of it's legs, we could all run at it like raging bulls then jump and cling to it while it followed it's inertia back to the ground.
well... one day at home doing the very same thing I had did at the birthday party, I feel that I may very well have tempted fate beyond it's patience that day, as I jumped on the vertical trampoline like many other times, although this time as the trampoline started to move forward, it suddenly stopped moving forward like it had stopped right at the cusp of it's transition then while holding the trampoline mat, the trampoline went in it's opposite direction right on top of me, honestly the worst bit was landing on the ground while clinging to the trampoline like I did a belly flop into a pool only on my back.
The air was knocked right out of my lungs when that happened, it was like getting kicked by a horse, if you were to see how it looked then it would be of a kid with a trampoline on top of them squirming around in the front of the yard trying to crawl out of the polypropylene mat, house beside them and green grass around the trampoline, top fifteen embarrassing moments of my life there...It took a while to get up after that also this is only one of the many accidents I've had with a trampoline.
So yeah, use trampolines at your own discretion btw both trampolines had no foam guards at the side of the springs and no safety nets, at the party a lot of us would hang onto the springs as we would fall towards the ground.
same, I tried to pat it but it bit my hand when I reached out to pat it
